Log Message:
py-dateutil: updated to 2.8.2

Version 2.8.2 (2021-07-08)
==========================

Data updates
------------
- Updated tzdata version to 2021a.

Bugfixes
--------
- Fixed a bug in the parser where non-``ValueError`` exceptions would be raised
  during exception handling; this would happen, for example, if an
  ``IllegalMonthError`` was raised in ``dateutil`` code.
- Fixed the custom ``repr`` for ``dateutil.parser.ParserError``, which was not
  defined due to an indentation error.
- Fixed a bug that caused ``b'`` prefixes to appear in parse_isodate exception
  messages.
- Make ``isoparse`` raise when trying to parse times with inconsistent use of
  `:` separator.
- Fixed ``tz.gettz()`` not returning local time when passed an empty string.

Documentation changes
---------------------
- Rearranged parser documentation into "Functions", \ 
"Classes" and "Warnings and
  Exceptions" categories.
- Updated ``parser.parse`` documentation to reflect the switch from
  ``ValueError`` to ``ParserError``.
- Fixed methods in the ``rrule`` module not being displayed in the docs.
- Changed some relative links in the exercise documentation to refer to the
  document locations in the input tree, rather than the generated HTML files in
  the HTML output tree (which presumably will not exist in non-HTML output
  formats).

Misc
----
- Moved ``test_imports.py``, ``test_internals.py`` and ``test_utils.py`` to
  pytest.
- Added project_urls for documentation and source.
- Simplified handling of bytes and bytearray in ``_parser._timelex``.
- Changed the tests against the upstream tz database to always generate fat
  binaries, since until GH-590 and GH-1059 are resolved, "slim" zic \ 
binaries
  will cause problems in many zones, causing the tests to fail. This also
  updates ``zoneinfo.rebuild`` to always generate fat binaries.
- Moved sdist and wheel generation to use `python-build`.
